Objectives : The aim of this study is to analyze the effect of acupuncture and the details of acupuncture treatment methods on skin wrinkles. Methods : Search was conducted in Pubmed, KISS, and NDSL databases for acupuncture studies on skin wrinkles. The detailed therapeutic techniques of acupuncture used for skin wrinkles and the effect of acupuncture on skin wrinkle improvement were analyzed. Then, the study results using the same indicator were compared through meta-analysis in order to compare the effects of acupuncture with the control group. The quality of randomized controlled trials (RCTs) was assessed using the risk of bias (ROB) assessment tool (Ver. 1.0, Cochrane Collaboration). Results : A total of 10 RCTs and 19 case series were included in this study. The most frequently used therapeutic technique for skin wrinkle improvement was Microneedle therapy system (MTS, n=19), and they were mostly used with aesthetic solutions (13 out of 19 studies). Skin wrinkle related indexes were most commonly used to evaluate skin wrinkle improvement (n=14). Panax Ginseng pharmacopuncture showed the most remarkable effect in improving the range of skin wrinkles and the depth of skin wrinkles. MTS+epidermal growth factor improved the levels of skin hydration, skin elasticity, and variation of skin pigment the most. MTS+Endothelial precursor cell improved the number of skin melanin the most. Three RCTs included in the meta-analysis showed moderate ROB on average. Conclusions : Acupuncture treatment was effective in improving skin wrinkles. However, a precise study design using unified indicators and appropriate controls needs to be performed in further studies in order to establish more convincing evidence of the effectiveness of acupuncture for improving skin wrinkles.

The purpose of this study was to investigate the effect of $7-MEGA^{TM}$ 500 on the improvement of skin aging in an UVB-induced photo-aging model of hairless mice. The dorsal skin of hairless mice was exposed to UVB three times a week for 12 weeks to induce skin wrinkle. After inducing the wrinkle, $7-MEGA^{TM}$ 500 was orally administered once a day for 4 weeks. Skin thickness, skin barrier function, and wrinkle indicators were improved by treatment with $7-MEGA^{TM}$ 500. Both gene and protein expression levels of MMP-3 and c-Jun in skin were significantly decreased by $7-MEGA^{TM}$ 500. Therefore, the intake of $7-MEGA^{TM}$ 500 is thought to have a positive effect on the improvement of skin aging, although further studies are needed.

The purpose of this study was to investigate the effects of Cuscuta chinensis Lamark ethanol extract (CL) on wrinkle improvement. Cuscuta chinensis Lamark is known to contain dried saccharide, alkaloids, flavonoids, lignans and rein glycoside as major components of dried mature seeds of Cuscuta japonica Choisy. In this study, we evaluated the anti-wrinkle effects of CL and investigated bio-markers (e.g ; MMP-1, MMP-3, MMP-9, TIMP-1, type I procollagen) associated with skin wrinkle improvement. We tested the anti-wrinkle effect of CL using human fibroblast called CCD-986Sk cell. We observed an increase in MMPs, TIMP-1, and type 1 pro-collagen CL in CCD-986Sk cells irradiated with UVB at an intensity of $2mJ/cm^2$ for 60 seconds. As a result, CL decreased UVB-induced MMPs levels and mRNA expressions in CCD-986Sk cell. The levels and mRNA expressions of type I procollagen and TIMP-1 were increased by CL. These results suggest that CL has activities on improvement of skin wrinkle, which is induced by UVB radiation. Taken together, this study proposed the possibility of developing herbal medicine and functional herbal cosmetic materials with wrinkle-improving effects of Cuscuta chinensis Lamark.

This study was to suggest the method for wrinkle improvement using Mugil cephalus extract. In order to evaluate the cosmetic product made of M. cephalus extract, the experiments were conducted with subjects and skin states for 4 weeks. Effect of cosmetics containing M. cephalus extract on the water holding capacity and evaporation of the women skin were investigated. The water holding capacity was increased after 1 h of application. But after 2 h, it was decreased. In the case of the water evaporation, it was increased with the increase of time. On the clinical trial, it was also found that water, oil, and rough level on the women skin were increased and wrinkles were improved. Side effects were also not detected during the application and treatment of cosmetics. Based on this result, the application of M. cephalus extract had positive effects on the improvement of wrinkles and skin in women. Therefore, it will be used to develop the wrinkle improvement therapy for women.

Bone morphogenetic proteins (BMPs) have diverse and important roles in the proliferation and differentiation of adult stem cells in our tissues. Especially, BMPs are well known to be the main inducers of bone formation, by facilitating both proliferation and differentiation of bone stem cells. Interestingly, in skin stem cells, BMPs repress their proliferation but are indispensable for the proper differentiation into several lineages of skin cells. Here, we tested whether BMP antagonists have an effect on the prevention of wrinkle formation. For this study we used an in vivo wrinkle-induced mouse model. As a positive control, retinoic acid, one of the top anti-wrinkle effectors, showed a 44% improvement compared to the non-treated control. Surprisingly, bone morphogenetic protein receptor 1a extracellular domain (BMPR1a-ECD) exhibited an anti-wrinkle effect which was 6-fold greater than that of retinoic acid. Our results indicate that BMP antagonists will be good targets for skin or hair diseases.

Inositol and phytic acic extracted from rice bran were investigated for applying cosmetics. Skin lotions containing 0∼3.0wt% inositol and 0∼1.5wt% phytic acid were applied respectively, to the arm skins of 45 Asian women 20'-40's for 7 weeks. Improvement on moisture was evaluated. In addition, improvements on sebum, elasticity, and wrinkle were examined after applying placebo, Inositol and phytic acid-containing skin lotions for face, respectively. For 1.0 wt% inositol resulted in 19% increase of moisture. The wrinkle reduction and elasticity improved 12.4% and 17.0% on average, respectively. Applying 0.5wt% phytic acid resulted in 71.6% increase the moisture. Improvements on wrinkle and elasticity were 15.9% and 21.9% respectively. Applying inositol or phytic acid regardless of dry or oily, resulted in sebum value recovery to that of the normal skin after 2- 4 weeks. Inositol is inferior to phytic acid in improvenients of the skin, and phytic acid is not suitable to sensitive skin. So 0-0.5wt% of phytic acid were added to 1.0wt% inositol and similar experiments were carried out. In case of added 0.1wt% phytic acid, moisture increased 63.8% approximately. Improvements on elasticity and reduction on wrinkle were 17.2% and 17.4%, respectively. Both skin types were turned to normal skin type after 2 weeks. It could improve the skin condition when used inositol added phytic acid. The optimized concentration of phytic acid was 0.10wt% with 1.0wt% of inositol for synergic effect.

The prime objective of many facial wrinkle-reduction treatments is to achieve visible improvement. Thus the visibility of before/after treatment differences is often part of an efficacy assessment. This paper investigates whether the background knowledge of the people acting as observers in such assessments is of impact on the results: e.g. the subjects themselves are familiar with their faces, skin professionals have much experience in judging skin quality, and thus both might be more sensitive to small changes. In a clinical study 44 Female subjects were regularly treated during a period of 12 weeks with one of three wrinkle-reduction methods: K, Land M (placebo). Photographs were taken before treatment and at 6 and 12 weeks. The photographs were judged by 3 types of observers:ㆍ24 Lay observers were given the 0＆6-week and the 0＆12-week photo pairs of all subjects to indicate the one with the least wrinkles in a two-alternative forced-choice (TAFC) procedure.ㆍThe subjects themselves were given the 0＆6-weel and the 0＆12-week pair of their own photos (8 replications) to indicate the photo with the least wrinkles (TAFC).ㆍA trained panel of skin professionals (N=3) each gave 9-point Fitzpatrick wrinkle-severity scores for all individual 0-week and 12-week photos. We found that the lay observers perceived the same differences as the subjects themselves: significant improvements after 12 weeks for treatment K (p<0.0005 and p=0.005, respectively), no visible effects for treatments Land M, and, most importantly, a significant difference between treatments K and M/placebo (p=0.02 and p=0.04, respectively). Also the trained panel found this difference between K and M (p=0.013), but here it was due to a significant deterioration over time of the 'placebo-treated' wrinkles (M, p=0.03). Thus in conclusion we have found no indications that extra knowledge - in the form of familiarity with the own face or in the form of professional training - results in the identification of more treatments that show significantly visible wrinkle-reduction.

본 연구에서는 경피 흡수가 어려운 주름 개선 펩티드인 GHK, GHK-Cu, Pal-GHK 리포좀 및 여기에 피부 투과 펩티드인 아르지닌 올리고머 R4(tetra-D-arginine), R6(hexa-D-arginine)를 첨가한 리포좀으로 경피 투과도를 측정하여 그 결과를 다음 6가지 구분으로 분석하였다. (1) 주름 개선 펩티드만 함유한 GHK, GHK-Cu, Pal-GHK lioposome의 경우; 24시간 최종 누적 경피 투과율은 6.05%, 7.4%, 8.83%를 보였다. (2) GHK에 약물 전달 펩티드 아르지닌 올리고머 R4, R6를 첨가한 리포좀의 경우; 24시간 최종 누적 경피 투과율은 13.63%, 7.68%를 나타냈다. (3) GHK-Cu에 R4, R6를 첨가한 리포좀의 경우; 24시간 최종 누적 경피 투과율은 15.46%, 8.64%로 나타났다. (4) Pal-GHK에 R4, R6를 첨가한 리포좀의 경우; 24시간 최종 누적 경피 투과율은 16.9%, 10.67%를 보였다. (5) GHK, GHK-Cu, Pal-GHK에 각각 R4를 첨가한 리포좀의 경우; 24시간 최종 누적 경피 투과율은 13.63%, 15.46%, 16.9%를 나타냈다. (6) GHK, GHK-Cu, Pal-GHK에 각각 R6를 첨가한 리포좀의 경우; 24시간 최종 누적 경피 투과율은 7.68%, 8.64%, 10.67%로 나타났다. 본 실험을 통해 구리이온(Cu2+)과 팔미트산에 의해 GHK의 피부 흡수가 증가하고, 피부 투과 펩티드에 의해 주름 개선 펩티드의 피부 흡수가 증진되며, GHK, GHK-Cu, Pal-GHK에는 R4가 R6보다 높은 효과를 보이는 것을 알 수 있었다. 이를 통하여 GHK, GHK-Cu, Pal-GHK의 피부 흡수를 증가를 위한 최적의 조건을 제시하여 그 효능을 극대화할 수 있는 방안을 제시함으로써 주름 개선 기능성 화장품에서의 폭넓은 활용과 응용을 제안한다.
